Abstract

The invention concerns a support comprising at least a blank made of a substantially rigid and pliable material comprising the display surface (11), stress means (10, 20, 21) for providing the blank display surface (11) with a convex shape and means (9, 19, 5) for maintaining the convex shape of the blank display surface (11) countering the stress means (10). The maintaining means countering the stress means (10) for maintaining the convex shape of the blank display surface (10) are designed so that their action is discretely distributed along the display surface of the blank (11) through a plurality of strips (9).

Description

Figure 4 is a rear view in an enlarged view of part of the frame from Figure 2 in the design of the information display device; and

Figure 5 is a perspective view of the rear part of the third embodiment of the framework of the invention in the design of the information display device in a slightly disassembled state.

The frame 1 for the information display device of Figure 1 has the form of a vertical column, which is unfolded, but which can be folded by folding the panels 2 on top of each other along the thick folding lines Z, of which there are therefore three here, made on a sheet made here of cardboard, which forms it, in this case there are four panels next to each other. All panels 2 are identical to each other. It is the front face surfaces of the panels 2 that form the surface 11 of displaying information on the support column.

Each panel 2 is extended on both sides in the transverse direction respectively by two edges, one of which is a hinge edge 4 and the other a stop edge 5. At their two longitudinal ends 6, 7 in the edges 4, 5 slots are made to allow the panels 2 bend over each other. The edges 4, 5 in the unfolded state of the information display device are bent to the rear front surface 8 of the panel 2 near the areas of the side edges 12, 13 of the display surface 11.

The edges 4, 5, respectively, serve as a hinge and a stop to the retaining strip 9, which in the design of the information display device makes it possible to force the panel 2 together with the elastic element 10 to bend its display surface 11 and keep it in this state thanks to the stopping edge 5, which can be is represented as the one located opposite the elastic forcing element 10.

At the same time, it will be noted that the retaining strips 9, despite the fact that in this case they are relatively wide, do not transmit their effect along the entire height of the column; this action is transmitted according to a discrete distribution along the entire height, that is, along the display surface of the sheet.

Each retaining strip 9, on the one hand, is hinged to the corresponding hinge edge 4 and, on the other hand, is introduced by its elastic element 10 into contact with the complementary stop edge 5.

Each strip 9 has a length smaller than the width of the panel 2, in particular to allow it to be bent.

Near the side edge 12, in the hinged edge 4, two slits 14, 15 are made in the form of loops, which receive two lugs in the form of a key, which protrude in the transverse direction from the section 18 of the hinged border section of the retaining strip 9. On the retaining strip 9, a cutout 20 of an elongated type is made for holding the elastic element 10 near the opposite limit stop section 19 of the retaining strip 9, while on the stop edge 5 for holding the elastic element 10 on it and therefore on the panel 2, a complementary cutout 21 is made in the form of an arc-shaped section.

From the unfolded or unfolded state of Figure 1, the frame for the information display device can be assembled by bending the panels 2 on top of each other with the help of their respective retaining strips 9.

For this purpose, the panels 2 are aligned by bending the elastic elements 10, while the abutment sections 19 of the retaining strips 9 move away from the abutment edges 5, and then the panels 2 are superimposed on each other along the assembly lines C alternately on one side and the other in the form of an accordion until held in this method by any suitable means, for example, an elastic element, a prefabricated structure folded.

Decomposition occurs even more simply by removing the elastic element that holds the frame in a folded state under the action of elastic forcing elements 10, which tend to place the resistance areas 19 of the strips 9 of the resistance edges 5 of the display surface 11 closer to each other and therefore to the bending of this surface 11 , while the prefabricated structure has the ability to simply unfold or unfold to take the form of the column from Figure 1.

It will be necessary to note that the bending of the lower panel 2, which has a support edge 22, which is accordingly curved, allows this panel 2 in combination with the lower edges without cutouts of the lower edges 4, 5 to perform the function of the support rack. However, a true holding post, such as that described in the above-mentioned prior documents, would be envisaged.

The frame sheet for the information display device that has just been described, and which has only one display surface 11, has a width approximately equal to half the width of a standard format sheet.

The sheet in figure 2 is intended for the manufacture of a frame for an information display device, which, as in the previous case, has two display surfaces 111 and 211 with two rows of panels 102, 202 on each side of the assembly lines 103, 203. This is a sheet of standard format, in which the pre-marked lines are made before their transition to two sheets 31, 32 along the longitudinal middle line 30 of the initial sheet.

Near the middle line 30, hinged edges 134, 234 with cutouts as in the example embodiment of figure 1 are pre-defined, which will bend relative to the side edges 112 and 212 of the face surfaces 111 and 211. The cutouts are formed by a diamond-shaped perforated hole 33.

Hinged slots 114, 214 are provided along the side hinged edges 112, 212 in the hinged edges in order to hinge the retention strips 39. The hinged slots correspond to the hinges 14, 15 in the embodiment of Figure 1 with a single display surface.

The abutment edges 135 and 235 with cutouts are pre-marked on the sides away from the hinge edges 134, 234, which will bend near the side edges 113 and 213 of the face surfaces 111 and 211. Two cutouts 321 and 322 in the form of arc-shaped sections are made starting from the edge 36 abutment edges 135 and 235 in order to retain the resilient retaining elements 110 (Figure 4).

The retaining strips 39 (Figure 3) of this second version are significantly different from the previous ones. First, they are much narrower, and secondly, their hinge edge 118 and stop edge 119 contain retractable elements capable of being inserted into the hinge slots 114, 214. Finally, their stop edge 119 performs somewhat more properly the function of a stop, which is the opposite of forcing functions of elastic elements 110.

Thus, the hinged edge 113 of each retaining strip 39 has a retaining strip 40 perpendicular to the longitudinal direction of the assembly structure and provides two internal retaining flanges, which are made on the adjacent edges 41, 42 of the strip, which engage with external retaining flanges, which are made on the same edges the strip and the transverse edges of two small ribs 43, 44, which can bend downward along the strip relative to this same edge 41, 42 in order to clamp the strip and all of the aforementioned between the strip 40 and the ribs 43, 44 in a lock, the two hinged edges 134, 234 of the two display surfaces 111, 112 (Figure 4) after the transition of the ribs to the bent-down position through the corresponding hinge slots 114, 214 of the two sheets and after the subsequent deployment of the ribs.

The abutment edge 119 of each retaining strip 39 has bent downwards along the longitudinal edges 41, 42 two small lugs 45, 46 for the passage and retention of a corresponding elastic member 110, which is held between the front parts 47 and the rear parts 48 and is pushed under the rear parts 47 and above the rear parts 48 (Figure 4).

In front of the stop edge 119, the strip 39 has a slot 49 in the form of a circular arc in order to hold the elastic element 110 on the strip.

Due to the fact that the elastic member 110 lies between the strip 39 and the front parts 47 of the lugs 45, 46, the edge 119 of the strip has a certain thickness, which provides a good means of abutment against the edge 36 of the downwardly bent abutment edges 135, 235 of the two display surfaces 111, 112.

The frame in Figures 2-4 can be assembled quite easily. After inserting the retaining strips 39 in the above-mentioned manner into the hinge slots 114, 214, and thus clamping the hinge edges 134, 234 together, the two sheets 31, 32, thus pressed against each other, are folded against each other, and then attaching each elastic element 110 to its corresponding retaining strip 39 by means of a slot 49, it is attached to two abutment edges 135, 235 superimposed on each other by means of slots 321, 322, thus drawing the strip 39 to the edges until the edge 119 abuts the edge 36 edge, then both face surfaces 111 and 112 are bent due to the shorter length of the retaining strips 39 in relation to their width.

The frame for the information display device of Figure 5 is completely similar to the frame of Figures 2-4 in that it in particular has two separate display surfaces 311, 312 provided for bending under the action of elastic forcing elements, which are not shown, but perform the same function as the elastic elements 110: in this case, the retaining strips 339 are absolutely identical to the retaining strips 39, which are also hinged to the two adjacent hinged edges 334, 434, which are also identical to the previous edges 134, 234 and to the two adjacent stop edges 335, 435, which are again identical with edges 135, 235.

The frame in Figure 5 differs, on the one hand, in the fact that the two separate information display surfaces 311, 312 of traditional width belong respectively to two sheets 301, 401 of a standard format, each of which contains a first section corresponding to the display surface and a second section 302 . action of the second row of tension wires 310 on each of the levels of the bending panels 502, 602, fixed at three points, and two points a, B are located on two intersecting edges 303, 403, and one point c - on the retaining strip 339.

Wires 310 can be made of plastic. Strips can be used instead of wires.
